I prefer just getting those bugs addressed. A lot of times writing these blogs and open letters just brings some attention to the blog/article and the real issue never gets addressed. Plus at least 2 of these would involve me sharing internal details which I prefer doing only through the official bug reporting channels.
> Apple has a team of at most 12 people working on TCP/IP and IPv6
Do you know who they are and how to reach them? I have filed 3 or 4 bugs with proper reproducers through Apple's feedback assistant over the years and till this day those issues haven't even received a single comment nor any acknowledgement that the report has been read.
